Fig. 6 is a detail frame 1, and braced by a bar 25, and said wheel 13 is slidably secured to the shaft 17 and has a friction ring 27 secured in the periphery thereof for traversing the face of the friction disk 7.

e The mechanism for sliding the clutch 16 and the wheel 13, comprises the lever head 28 pivotally and slidably mounted on a rod 29 secured to the standard 23 and to the yoke 24, and said head has a curved arm 30 from which extends the hand lever 31, and' 43 on the same face of the link as the pins 34. The bolt is cushioned by a spiral spring 44 surrounding the bolt and abuttingagainst a bolt nut 45, and the side of the standard, soas to permit the link to he slid and yet prevent accidental sliding of the link.

A plate 46 is secured in proper position relative to the hand lever 31, and said plate is provided with a slot 47 having offset slots 48 and 49. The lever 31 is moved to one end of the slot 47 for high speed and to the other end of the slot 47 for low speed. The lever 31 is slid into the offset slots 48 and 49 for holding the lever to high and low speed positions. The slots 48 and 49 permit sufiicient movement of the lever 31 and the head 28 along the rod 29 for the portion 30 of said lever to engage between the pins, 20, whereby when the lever 31 is given pivot movement the clutch element 16 is moved. \Vhen the head 28 is given sliding movements on the rod 29 the lug 33 enga and disengages the link pins 34, and the pivot movement of the lever 31 and the head 28 while the lug is engaged with the pins 34 slides the link 36 which moves the lever '37, for sliding the wheel 13. The clutch element 16 remains in engagement with the gear 14 during the progress of the lever 31 in the slot 47, and the lever is slid into the offset slots 48 and 49 for transmit ting power at reverse speeds.

\\'e do not wish to be understood as confining our invention to any particular size, shape or material, nor do we wish to limit ourselves to any particular means for assei'nbling the parts thereof, or in the scope of n-actical application of the invention, but reserve the right to make such changes and various arrangements as may come within the scope of the appended claims without departing from the spirit of the invention.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is 1. In transmission mechanism for motor vehicles, a driving shaft, a pair of bevel gears loosely mounted on the shaft, clutch elements on said gears, a clutch element attached to and slidable on the shaft, a driven shaft slidably connected with the driving shaft, a friction disk secured to the driven shaft, a shaft perpendicular to the said shafts and having a pinion engaging the bevelgears, a friction wheel slidably secured to the perpendicular shaft for engaging the disk, and means for sliding the clutch element and the friction wheel at right angles comprising a clutch lever, a sliding and swinging hand lever engaging the clutch lever, and a pair of connected levers one of which engages said Wheel and the other of which is operated by the hand lever.

2. In transmission mechanism for motor vehicles, a driving shaft, a pair'of bevel gears loosely mounted on the shaft, clutch elements on said gears, a clutch element attached to and slidable on the shaft, a driven shaft slidably connected with the driving shaft, a friction .disk secured to the driven shaft, a shaft perpendicular to the said shafts and having a pinion engaging the bevel gears, a friction wheel slidably secured to the perpendicular shaft for engaging the disk, a pair of levers pivoted together for sliding movement at right angles, one of said levers being attached to the friction wheel, a clutch lever, and a swinging hand lever engaging the clutch lever and having slidable engagement with the other lever of said pair of levers.

3. In transmission mechanism for automobiles, a driving shaft, a pair of gear wheels loosely mounted on the shaft, a clutch attached to and slidable on the shaft between the gears for engagement therewith, a driven shaft slidably connected with the driving shaft, a friction disk secured to the driven shaft, a shaft perpendicular to'the said shafts and having a pinion engaging the gear wheels, a friction wheel slidably secured to the perpendicular shaft for engaging the disk, a lever projecting from the friction wheel, a clutch lever having pins, a hand lever engaging between said pins for operating the clutch lever, and
